The 'Applause' hitmaker ditched her usual grunge style and took to the stage in a cute polkadot latex leotard and fishnet tights at the BB&T Center in Fort Lauderdale before going through a number of costume changes.

She later opted for a shoulder-length platinum blonde wig and futuristic white gown, a jewelled leotard with a blue orb in the centre of her chest, and also dressed up as a giant squid in another polkadot number.

The 27-year-old star, who is touring to support her 'ARTPOP' album, took to Twitter ahead of her first show and posted: ''I can't believe the show is tonight, been dreaming about it since I wrote the first song for the album. I love you monsters. LETS PARTY (sic).''

Gaga performed hits such as 'Just Dance', 'Bad Romance', 'G.U.Y', 'Swine', and 'Applause', along with her new song Donatella, which she sang for the first time in honour of her fashion designer friend, Donatella Versace, and another new track, Partynauseous.

The singer later described her sold out show as one of the ''most incredible experiences of my life'' and praised her fans, nicknamed 'little monsters'.

Gaga wrote: ''I have to hand it to little monsters in ft Lauderdale. Your fashun was AMAZING MAGICAL AND I WAS SO HAPPY TO SEE YOUR PRETTY FACES. (sic)''

The singer will continued her tour tonight (06.05.14) in Atlanta, followed by a number of US shows in the likes of Madison Square Garden in New York and the Staples Center in Los Angeles before moving onto the UK.
